Clothing

It used to be that tech events only had t-shirts in sizes L, XL, and XXL. Women like me yelled enough so that they now go to their shirt jobbers and say, "Give me shirts for girls, too." So these days, tech events have t-shirts that fit Men's L, XL, and XXL, and t-shirts that fit girls ages 7 through 11. Be different; please order shirts in Women's sizes, too!

+1 for stressing women's sizes. I can't tell you how fed up I am with corporate polo shirts that are big enough for me to wear as a dress. Also, for those of you in charge of swag, when we say women's sizes, we don't just mean smaller, we actually mean "shirts with cuts that fit women". Don't just order men's shirts in XS, noone except small guys will ever wear them.

... As nice as they are, I haven't seen any (reasonably priced) good branded ones... Nearly every branded/promotional stick I have got from a trade show are cheap/slow and break after you use them a bit... Not saying I would say no to one, but I would rather have a few hundred stickers or a t-shirt for the price of one stick!

I'd be in favour of something nice, original and small to attach to your monitor or laptop case, preferably without the logo so it's not too obvious. A mascot of sorts, with a clip mechanism allowing it to be attached to any object of a certain width. I thought of Homer Simpson's Springy because of the SO logo's resemblance of a spring. Or something to that effect.

A nice little insider gag for people to talk about, and do a tiny little bit of bragging. Say for example, every user gets one once they surpass 10k rep. So if you see a guy with a SO mascot on their laptop case, you know they're a fellow stackhead.

Hmmm, badge count, that asks for something with a little display and wifi connection...

Surely someone could change this alarm clock to show reputation, and above all: wake you up when you're downvoted, or wake you up an hour earlier if reputation growth is too low! (Or a chumby or something like that.)

Since the holidays are coming up soon, why not finally give this question and its answers (10k+ only, sorry) a proper place in Stack Overflow history by using it to print wrapping paper? It could be sold in packs of 10 sheets at an appropriate size to wrap the average gift.

Customized high-quality business cards might be an interesting guerrilla way to promote the careers site.

Say, give every user above a certain reputation (or something) the chance to order a 100 pack of really high-quality (embossed?) business cards. They can define the contents themselves, with the condition that the web link points to their SO careers profile.

I'd go for T-shirts with small logos. (I dislike all my tech T-shirts with huge logos, I don't mind being an advertisement, but I don't really want to be a whore. :)

Also, static vinyl car window stickers. Something that can be easily removed and won't leave a gigantic pile of adhesive gunk. Something that sticks on the inside of windows, so it looks good for years.
